When a user confirms an account-linking request from a different browser, a temporary proof is created to validate the link. However, this proof is not properly cleared after the link is established or when the user later manually removes the link. An attacker who controls the external identity can exploit this leftover proof to silently re-establish the link and gain unauthorized access to the victims account without any further confirmation.","score":6.4,"severity":"medium","published":"2026-09-16T05:50:26.094Z","modified":"2026-11-06T10:25:46.338Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Red Hat","name":"Red Hat build of Keycloak 26.6.8","platforms":[],"versions":[],"defaultStatus":"unaffected","cpes":["cpe:/a:redhat:build_keycloak:26.6::el9"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-92358"},{"vendor":"Red Hat","name":"Red Hat build of Keycloak 26.6.8","platforms":[],"versions":[],"defaultStatus":"unaffected","cpes":["cpe:/a:redhat:build_keycloak:26.6::el9"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-92358"},{"vendor":"Red Hat","name":"Red Hat build of Keycloak 26.6.8","platforms":[],"versions":[],"defaultStatus":"unaffected","cpes":["cpe:/a:redhat:build_keycloak:26.6::el9"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-92358"},{"vendor":"Red Hat","name":"Red Hat Single Sign-On 7","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/a:redhat:red_hat_single_sign_on:7"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-92358"}],"remediation":[{"text":"Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.","source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-92358"}],"references":["https://access.redhat.com/errata/RHSA-2026:95761","https://access.redhat.com/security/cve/CVE-2026-92358"],"sources":[{"name":"CVE","id":"CVE-2026-92358","modified":"2026-11-06T10:25:46.338Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-92358"}],"assessments":[{"source":"redhat","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:N","score":6.4}],"sourceAffected":[],"observedAt":"2026-11-06T10:51:19.625Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T22:40:32.870Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-11-03T19:15:34.222Z","attemptedAt":"2026-11-03T19:15:34.222Z"},{"source":"GHSA","status":"available","checkedAt":"2026-11-03T19:15:34.079Z","attemptedAt":"2026-11-03T19:15:34.079Z"},{"source":"EUVD","status":"available","checkedAt":"2026-11-03T19:15:34.082Z","attemptedAt":"2026-11-03T19:15:34.082Z"},{"source":"EPSS","status":"available","checkedAt":"2026-11-03T19:15:33.676Z","attemptedAt":"2026-11-03T19:15:33.676Z"}],"evidence":[{"source":"FIRST EPSS","id":"CVE-2026-92358","url":"https://www.first.org/epss/","probability":0.00274,"percentile":0.19821,"date":"2026-11-03","checkedAt":"2026-11-03T19:15:33.676Z"},{"source":"ENISA EUVD","id":"EUVD-2026-80173","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-80173","modified":"Sep 17, 2026, 3:49:45 PM","score":6.4,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:N","checkedAt":"2026-11-03T19:15:34.082Z"},{"source":"GitHub Advisory Database","id":"GHSA-prm3-wvj6-64vx","url":"https://github.com/advisories/GHSA-prm3-wvj6-64vx","modified":"2026-09-16T06:31:47Z","score":6.4,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:N","checkedAt":"2026-11-03T19:15:34.079Z"},{"source":"NVD","id":"CVE-2026-92358","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92358","modified":"2026-09-17T16:18:32.643","score":6.4,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:N","checkedAt":"2026-11-03T19:15:34.222Z"}],"aiSummary":{"text":"A flaw in Keycloak's first broker login flow allows an attacker controlling an external identity to silently re-establish an account link.
